摘　　要：辽河油区目前面临资源接替紧张、大多数油田进入递减阶段、开发形势十分严峻的现实,科学合理地评价具有挖掘潜力油藏的开发效果,对油区的持续稳定发展起着举足轻重的作用。在分析该油区开发状况的基础上,提出了最具有挖掘潜力的复杂断块油藏的评价标准,并尝试应用模糊评判和未确知测度模型对其开发效果进行综合评价,从而形成一套完整的复杂断块油藏综合效果评价体系,应用效果较好。与实际开发对比,评判结果具有科学合理的优点。该评价体系提高了复杂断块开发效果综合评价的可信度,为该油区下步充分挖掘油藏潜力指明了方向,对其他类型的油藏开发效果评价也具有一定的借鉴作用。It is very important to evaluate the development effect which are potential for steady reservoir development in Liaohe Oilfield in view of the fact that the resource is difficult in the oiffield and the most of reservoirs have entered the descending phase based on analyzing development status of this district. This article puts forward the evaluating standards of complex fault-block reservoirs and attempts to evaluate the blocks with the fuzzy judging model and the unascertained measure model. So a completely evaluating system of the development effect of complex fault-block reseravior has been generated. This evaluating system is used to evaluate the complex waterflood reservoirs in the oilfield for the first time and the result is satisfactory. It possesses the excellence of scientific and reasonable evaluation.The reliability of synthetic evaluation development response of complex fault-block reservoir is improved. Meanwhile, it is also used as a reference to evaluating the development effect of other reservoirs.
